DE-SMOGER This invention relates generally to filtering systems and more particularly to novel and improved apparatus for filtering out objectable solids and gasses from exhaust gasses.

A principal object of the present invention'is to provide a apparatus which will clean up an exhaust gas from a combustion engine.

Another object of the present invention is to provide a apparatus which can be used on any type of equipment such as air-conditioning or filtering, automotive or on boilers and which can be utilized where any type of fuel is used such as gas, oil or coal.

Another object of the present invention is to provide a apparatus which can be built in a single unit or which alternately can be made in three separate units and which may be in any shape such as square or round so to be fully adaptable for any particular installation.

Other objects of the present invention are to provide a apparatus which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and.

efficient in operation.

These and other objects will be readily evident by a study of the following specification and the accompanying drawing wherein:

FIG. 1 is a side cross-sectional view of a preferred embodiment of apparatus in accordance with the present invention;

FIG. 2 is a top plan view thereof.

Referring now to the drawing in detail, the reference numeral represents a apparatus made, according to the present invention, wherein there is a tank or housing 11 having the interior thereof divided into three treatment chambers or compartments 12, 13 and 14.

The first compartment 12 has a quantity of liquid 15 placed therewithin and which may comprise any form of solvent for removing ash, carbon, soot or other solid particles from an exhaust gas 16 that is delivered into a lower portion of compartment 12 by a duct or pipe 17. The terminal end of the duct 17 in the lower portion of the compartment 12 is forked with a plurality of channels 18 each one of which has an exit port 19 in a horizontally spaced apart position so that the exhaust gasses are broadcast throughout the liquid 15, as the exhaust gasses bubble upwardly in small particles as indicated by the arrows 20.

A transverse extending screen 21 extends across the compartment 12 and is located within the liquid 15, the rack or screen 21 serving to support chemical nutrients 35 for aiding in the removal of the objectionable solid particles from the exhaust gas. At the lower end of the compartment 12 there is a downwardly extending hopper 22 which converges into a downwardly extending duct 23 and into which sediment 24 comprising the solid particles of ash, carbon or soot are deposited into a sludge sump which can periodically be pumped out. Chemicals deposited into the sludge sump during the process can be then recycled for returning and for subsequent use.

At the upper end of the compartment 12 there is an opening 25 in a side wall covered by a screen 26, the screened opening 25 leading to the compartment 13 and at its upper end thereof. In the compartment 13, the gasses purified from the compartment 12 may now be suitable for energy return to the engine or the fire box if so desired. A port 27 is accordingly provided therefor. The port 27 may additionally be utilized for the addition of neutralizers into the chamber 13 for mixing with the gasses coming from the chamber 12, the nutralizers serving to neutralize any poisonous or harmful gasses. Spray bars or gravity jets 38 may be utilized for mixing the neutralizers with the incoming gasses from the compartment 12. At thelower end of compartment 13 there is an exit opening 28 covered by a screen 29 and which leads to the compartment 14, the gasses thus moving downwardly in the compart ment l3 and then moving upwardly in the compartment 14 as indicated by the arrows.

In the compartment 14, an ozone gas from an ozone source 43 may be added by being discharged thereinto from jets 30 coupled to the source 43 and the compartment 14 may include magnetic means 39 for attracting metal particles, thereby removing them from the gas thus traveling upwardly and outwardly through the exhaust ports 31. The exhaust ports 31 are connected by means of ducts 44, to suitable fans 45 which thus cause the exhaust gasses to be circulated through the desmoger compartments. The lower end of the compartment 14 may be open as shown at 32 or being connected likewise to a suitable sediment collection unit from which the metal particles can then be removed.

Thus there is provided a apparatus which purifies the exhaust gas from a combustion engine that is fired either by gas, oil or coal and wherein the exhaust gas thus purified can then be either recirculated back to the engine or released into the atmosphere without danger of polluting the same.
